Question

A child grew 3 1/4 inches one year and 4 3/4 inches the next year. How many inches did the child grow over the two years?

Answer 1

Answer:

The child grew 8 inches

Step-by-step explanation:

Step 1:  Convert to improper fractions

$3\frac{1}{4}$

$\frac{1+(3*4)}{4}$

$\frac{1+12}{4}$

$\frac{13}{4}$

$4\frac{3}{4}$

$\frac{3+(4*4)}{4}$

$\frac{3+16}{4}$

$\frac{19}{4}$

Step 2:  Combine the fractions

$\frac{13}{4}+\frac{19}{4}$

$\frac{13+19}{4}$

$\frac{32}{4}$

$8$

Answer:  The child grew 8 inches

Answer 2

Answer:

8 inches.

Step-by-step explanation:

3 1/4 + 4 3/4

= 3 + 4 + 1/4 + 3/4

= 7 + 4/4

= 7 + 1

= 8 inches.
